The Spanish striker scored Chelsea’s opening goal yesterday in a 2-1 win at Leicester but the victory was marred when some travelling fans repeatedly sang: “Morata, whoa, Morata, whoa. He came from Real Madrid, he hates the f**cking Y**s.”

Chelsea’s management wasted no time in condemning the sick song and pleaded with their support to ditch it.

Blues coach Antonio Conte was unaware of the offensive lyrics but Chelsea’s Head of Communications Steve Atkins appealed to fans to heed their pleas.

He said: “I don’t think Antonio was aware of the song. The club and the players appreciate the fans’ passionate support away from home.

“But the language in that song is not acceptable at all.

“We’ve spoken to Alvaro after the game and he does not want to be connected with that song in any way and both the club and the player request the supporters stop singing that song with immediate effect.”

Chelsea’s next game is a Champions’ League home tie against Qarabag FK on Tuesday September 12 and any repeat of yesterday’s lyrics would sure to land the club in hot water and lead to sanctions from Uefa chiefs.

Conte’s men were in control from the off and had the game wrapped up when N’Golo Kante added to Morata’s opener on 50 minutes.

Immediately after the win at Leicester, before Morata was made aware of the unsavoury singing, he said: “It is important to win here.

“Always against Leicester at this stadium it is very difficult to win.

“We were in a good position at 2-0 but suffered to the end. This is the Premier League.

“I am good but the most important thing is we are not in the first places and we look forward to moving ahead in the table.”

Morata joined Chelsea from Spanish side Real Madrid for a club-record fee of £60 million. The striker has scored 3 premier league goals for Chelsea in the premier league.
